Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, and in particular to a microwave extraction device capable of multi-stage purification. Background Technology

[0002] Microwave extraction equipment is a device that uses microwave electromagnetic fields as a heating source to quickly "dissolve" the target components in a solid sample. It uses microwaves to penetrate the material, causing water, polar solvents, and polar groups in cells to rotate and rub at high speed simultaneously, instantly raising the temperature. Since the microwave extraction equipment is a sealed space, the pressure will also increase as the temperature rises. The cell walls will rupture due to the increased pressure, allowing the target components to rapidly diffuse into the solvent.

[0003] After extraction, the material residue needs to be separated from the solution. This requires opening the microwave extraction equipment, removing the container, and then separating the material from the solution and storing them in different containers.

[0004] However, at the moment the lid is opened, external air, moisture, and microorganisms come into contact with the materials and solutions, causing contamination and negatively impacting the quality of purification. Utility Model Content

[0005] In view of the above-mentioned problem that external air, water vapor, and microorganisms come into contact with the materials and solutions at the moment of opening the lid, causing contamination and negatively affecting the quality of purification, this utility model is proposed.

[0006] Therefore, the purpose of this invention is to provide a microwave extraction device capable of multi-stage purification. The extraction components are rotated by a turntable. During rotation, the auxiliary bar of the upper second container abuts against the baffle, stopping the second container from rotating while the first container continues to rotate. This causes the drain pipe to separate from the sealing plate, allowing the solution in the second container to flow into the first container. The first filter screen filters out material residue, and the second filter screen filters out impurities in the solution again. The above separation operation can be performed without removing the container, avoiding contact with the external environment, significantly reducing the risk of contamination, and improving extraction purity and process stability.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a microwave extraction device capable of multi-stage purification, including a microwave oven, a turntable is provided in the cavity of the microwave oven, an extraction component is placed on the turntable, and the turntable is used to drive the extraction component to rotate; The extraction component includes a first container, a second container placed on the upper end of the first container, a first filter screen provided on the periphery of the inside of the second container, auxiliary strips connected to the periphery of the first and second containers, a baffle fixedly installed inside the microwave oven cavity, a drain pipe connected to the lower end of the second container, and a sealing plate fixedly installed on the periphery of the inside of the first container.

[0008] As a preferred embodiment of the microwave extraction device capable of multi-stage purification described in this utility model, the second container is provided with a top cover at its upper end, the first container is provided with a second filter screen on its inner peripheral side, and the lower end of the second container is provided with a positioning groove.

[0009] In a preferred embodiment of the microwave extraction device capable of multi-stage purification described in this utility model, the turntable is connected to a drive assembly. The drive assembly includes a mounting bracket, which is fixedly connected to the microwave oven. The mounting bracket has a U-shaped plate structure. A drive motor is fixedly mounted on the mounting bracket. A drive shaft is fixedly connected to the output end of the drive motor. A drive gear is fixedly mounted on the circumferential side of the drive shaft. The drive gear meshes with a transmission gear. The transmission gear is fixedly connected to a transmission shaft. The transmission shaft is rotatably connected to the microwave oven. One end of the transmission shaft extends into the microwave oven.

[0010] In a preferred embodiment of the microwave extraction device capable of multi-stage purification described in this utility model, the other end of the drive shaft is rotatably connected to the mounting bracket, the size of the drive gear is larger than the size of the drive gear, and the end of the drive shaft extending into the microwave oven is fixedly connected to the turntable.

[0011] In a preferred embodiment of the microwave extraction device capable of multi-stage purification described in this utility model, a limiting component is provided on the upper surface of the turntable; The limiting component includes a base plate, which is fixedly connected to a turntable. A spring is fixedly installed on the base plate, and a plurality of springs are fixedly connected to a clamping plate. The turntable has a guide groove, which is slidably connected to the clamping plate.

[0012] In a preferred embodiment of the microwave extraction device capable of multi-stage purification described in this utility model, the substrate, spring, and clamp are symmetrically arranged in two sets, and the first container is located between the two clamps.

[0013] The beneficial effects of this utility model are: 1. This utility model uses a turntable to drive the extraction component to rotate. During rotation, the auxiliary bar of the upper second container abuts against the baffle, and the second container stops rotating, while the first container continues to rotate, causing the drain pipe to separate from the sealing plate. The solution in the second container flows into the first container, the first filter screen filters out material residue, and the second filter screen filters impurities in the solution again. The above separation operation can be performed without removing the components, avoiding contact with the external environment, significantly reducing the risk of contamination, and improving extraction purity and process stability.

[0014] 2. This utility model uses a spring to provide thrust, causing the two clamping plates to move closer to each other along the guide groove, thereby fixing the first container. This avoids the centrifugal force of the rotating turntable causing the first container to shift position, thus ensuring the stability of material and solution separation.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1:

[0021] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a microwave extraction device capable of multi-stage purification, including a microwave oven 1, a turntable 2 disposed in the cavity of the microwave oven 1, an extraction component 3 placed on the turntable 2, and the turntable 2 being used to drive the extraction component 3 to rotate. The extraction component 3 includes a first container 301, a second container 302 placed at the upper end of the first container 301, a first filter 303 provided on the periphery of the inside of the second container 302, an auxiliary strip 304 connected to the periphery of the first container 301 and the second container 302, a baffle 305 fixedly installed in the cavity of the microwave oven 1, a drain pipe 306 connected to the lower end of the second container 302, and a sealing plate 307 fixedly installed on the periphery of the inside of the first container 301.

[0022] The upper end of the second container 302 is provided with a top cover 308, the inner periphery of the first container 301 is provided with a second filter screen 309, and the lower end of the second container 302 is provided with a positioning groove 310. Example 2:

[0023] Reference Figure 4 This is the second embodiment of the present invention, which differs from the first embodiment in that the turntable 2 is connected to a drive assembly 4; The drive assembly 4 includes a mounting bracket 401, which is fixedly connected to the microwave oven 1. The mounting bracket 401 has a U-shaped plate structure. A drive motor 402 is fixedly mounted on the mounting bracket 401. A drive shaft 403 is fixedly connected to the output end of the drive motor 402. A drive gear 404 is fixedly mounted on the circumferential side of the drive shaft 403. The drive gear 404 meshes with a transmission gear 406. The transmission gear 406 is fixedly connected to a transmission shaft 405. The transmission shaft 405 is rotatably connected to the microwave oven 1, and one end of the transmission shaft 405 extends into the microwave oven 1.

[0024] The other end of the drive shaft 405 is rotatably connected to the mounting bracket 401. The size of the drive gear 406 is larger than that of the drive gear 404. One end of the drive shaft 405 that extends into the microwave oven 1 is fixedly connected to the turntable 2. Example 3:

[0025] Reference Figure 4 This is the third embodiment of the present invention, which differs from the second embodiment in that: a limiting component 5 is provided on the upper surface of the turntable 2; The limiting component 5 includes a base plate 501, which is fixedly connected to the turntable 2. A spring 502 is fixedly installed on the base plate 501. Several springs 502 are fixedly connected to a clamping plate 503. The turntable 2 has a guide groove 504, which is slidably connected to the clamping plate 503.

[0026] The substrate 501, spring 502, and clamping plate 503 are symmetrically arranged in two sets, and the first container 301 is located between the two clamping plates 503.

[0027] In use, the second container 302 is placed at the opening of the first container 301 through the positioning groove 310, and the auxiliary strips 304 of the first container 301 and the second container 302 are aligned, thereby ensuring that the sealing plate 307 blocks the drain pipe 306.

[0028] Push the clamp 503 to compress the spring 502, place the first container 301 in the center of the turntable 2. After releasing the clamp 503, the spring 502 returns to its original position and moves the clamp 503. The two clamps 503 fix the first container 301 in place, preventing the first container 301 from shifting due to centrifugal force when the turntable 2 rotates.

[0029] Microwave oven 1 is started to process the material. After processing, drive motor 402 is started. Drive motor 402 drives drive shaft 403 and drive gear 404 to rotate. Drive gear 404 drives transmission gear 406 to rotate, which in turn drives transmission shaft 405, turntable 2, first container 301 and second container 302 to rotate. When the auxiliary bar 304 of second container 302 abuts against the stop bar 305, second container 302 stops rotating, while first container 301 continues to rotate, causing drain pipe 306 to separate from sealing plate 307. The solution in second container 302 flows into first container 301. First filter screen 303 filters material residue, and second filter screen 309 filters impurities in the solution again.

[0030] The above separation operation can be performed without removing the materials, avoiding contact between the materials and solutions and the external environment, significantly reducing the risk of contamination, and improving extraction purity and process stability.

[0031] Multiple second containers 302 can be set as needed, and the same number of baffles 305 and first filter screens 303 with gradually decreasing filter apertures can be configured. The lengths of the auxiliary bars 304 and baffles 305 of the second containers 302 can be adjusted adaptively so that the second containers 302 stop rotating sequentially from top to bottom.

[0032] The remaining structure is the same as that in Example 1.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
